In case you hadn't noticed thats the very purpose of this thread. Also, accepted wisdom is that once something is used/secondhand then you are not going to get what you paid for it. Its called depreciation. You wouldn't expect to pay full retail value for your car if its 3 years old, with a load of upgrades you can't attest the veracity of. So why should people pay full asking price for your second hand AEG with a load of 'upgrades'. Noone cares what they cost, you will not get full RRP.
